Land Rover Battery price and warranty

I went to purchase a battery for my Land Rover in one of the Land Rover dealerships and they told me that the warranty for the battery is only six months if it is purchased on the counter. I refused to buy such an expensive battery from them, especially after considering the price and the warranty period. I then approached another prominent battery provider, and I purchased a reliable battery with a 25-month warranty at less than half of the price of Land Rover battery. It is ridiculous how JLR takes advantage of its customers. It seems to me that they don't trust their product.
